Code smell. SVGImageView.java uses Exception to handle multiplicity of "svg" attribute

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Declare the SVGImageView in a layout file (xml)
2. Specify an asset file using the "svg" attribute.

What is the expected output? What do you see instead?

The svg is rendered correctly and the app runs fine. However logcat is filled 
with Warnings for behavior that should be handled more gracefully and doesn't 
need warnings to be raised.

What version of the product are you using? On what operating system?

1.2 I think. I cloned the repo today.
Android 2.3.3 (API 10)

Please provide any additional information below.

One example is SVGImageView.internalSetImageURI(Uri uri) on line 138: is = 
getContext().getContentResolver().openInputStream(uri);

If one chooses to specify an asset file in the "svg" attribute than the uri is 
a string containing the relative path of the svg file in the assets/ folder. 
Clearly this will cause the above line to fail and throw an exception.

This behavior is expected however, based on how the "svg" attribute accepts 
multiple possible inputs (as defined in 
https://code.google.com/p/androidsvg/wiki/SVGImageView). Unfortunately the code 
captures the exception using a generic Exception (frowned upon behavior) and 
then writes a warning log (for expected behavior).

Solution:

Use specific Exceptions to catch the various possibilities and handle them 
accordingly. For instance I prefixed the general Exception catch with this 
single line:

catch (FileNotFoundException e) { return false; }

No more warnings for expected behavior.
